Chromatic Technologies Inc. (CTI) has announced development of patent-pending ‘reveal inks’ that provide “return to fridge” reminders to such vulnerable products as milk, yogurt, salsa, pickles and ketchup.
“Most parents know that food safety at home is a big deal, but they need help understanding how long they can keep something out of the fridge,” said Patrick Edson, CTI’s chief marketing officer. “
Food companies are understandably hesitant to put warning labels on their packaging, so the problem continues to exist. The simple solution is a ‘return to fridge’reminder that appears on packaging when the product starts to warm up and the product can become vulnerable to spoilage.When the temperature is fine, the reminder is ‘off.’ When the package is getting warm, the reminder turns ‘on,’”Edson added.
The U.S. Department of Agriculture’s Food Safety and Inspection Service recommends any refrigerated food should be discarded if it has been in temperatures above 40° F. (4.4° C.) for over two hours.CTI’s “reveal inks” can be printed cans, paper labels, cartons and film and is powered by a combination of thermochromic inks.
When the product, such as milk, is at a safe temperature, the message reads “Drink Milk,” but when the carton reaches a target warm temperature (e.g., 40° F. or4.4° C.), a color will disappear revealing a “return to fridge” reminder to the consumer.
CTI’s process allows the message, which is enabled to be ‘on’ and ‘off’ throughout the life of the package, to be customized.
In 2011, the most sweeping reform of America’s food safety laws in more than 70 years was enacted as President Obama signed America’s“Food Safety ModernizationAct” (FSMA).
Overseen by the U.S. Food and Drug Administration, the Act aims to ensure that America’s food supply is safe by shifting the focus from responding to contamination to preventing it.
Lack of proper refrigeration conditions can result in such medical challenges as Bacillus cereus, Clostridium perfringens,Salmonella and Staphylococcus, according to the U.S. Department of Health & Human Services.
Since its founding in 1993, CTI has been dedicated to improving lives “through chemistry that alerts, protects and surprises.” As the world’s largest manufacturer of thermochromic inks, CTI uses its ink technology to convey messaging, be it an indication of hot or cold temperatures, or an extension of the product’s brand.
CTI chemistry also provides photochromic, black light, glow-in-the-dark, social media activation, security protection, and is also inventing new methods for bacteria detection and cancer treatment.
CTI’s innovations can be found on products from such companies as Anheuser-Busch, Coca-Cola, Coors, Fanta, Hallmark, Heineken, Monster Energy, Mountain Dew, Pizza Hut and Tuaca Liqueurs
